1. Safety rules
Terminal box type ZENITH P are designed as Group II category
2 Equipment and is suitable for use for fixed installation in areas
with explosion hazard designated Zone 1 or Zone 2 to EN 60079-
0, or Zones 21 or Zone 22 to EN 61241-0.
These operating instructions must be kept in safe place for later
consultation. During operation, do not leave this instruction
manual or other objects in the enclosure.
Operate the terminal boxes type ZENITH P only for their intended
duty in the undamaged and clean condition, and only where the
resistance of the material to the surroundings is assured.
The enclosures are designed to withstand an impact of 7 J, and
to be used in normal conditions of vibration. They are not
designed for use in areas subject to intentional or extreme
conditions of vibration.
Enclosures are made of carbon loaded glass reinforced
polyester. The enclosures have a surface resistance between 10
and 10
9
Ω. They do not present a hazard from static electricity.
In the event of incorrect assembly, the type of protection will no
longer be assured.
Only genuine SCAME spare parts may be used for replacement.
No modifications are allowed to the terminal boxes that are not
expressly mentioned in this instruction manual.
DO NOT OPEN THE ENCLOSURE WHEN ENERGISED IN
PRESENCE OF EXPLOSIVE ATMOSPHERE
Whenever work is done on the terminal box, be sure to observe
the national safety and accident prevention regulations and
the safety instruction given in this instruction manual.

The ambient temperature is marked on the label.
The equipment is certified in ambient temperature in the range:
-50°C to +40°C
-50°C to +60°C
-50°C to +75°C (not for 644.0380 and 644.0390)
or if suitable terminals are used:
-60°C to +40°C
-60°C to +60°C
-60°C to +75°C (not for 644.0380 and 644.0390)
and should not be used outside these ranges.
When supplied with terminals complete of wiring cables,
the boxes have been submitted to the dielectric test in
accordance with the clause 6.1 of EN 60079-7.When supplied with
terminals without wiring cables, the dielectric test must be
performed by the installer.
4. Installation
Installation shall be carried out by suitably-trained
personnel in accordance with the applicable code of
practice (e.g. EN 60079-14 and EN 61241-14) and the provisions

Before opening the enclosure verify that the surrounding atmosphere
6
is not dangerous (see EN 60079-17 and EN 61241-17) or switch off
main supply. It is also necessary to ensure that there is no voltage,
or take suitable protective measures. The electrical connection of the
device may only be carried out by skilled staffperson.
4.1 Conditions of Safe Use
The IP rating shall be maintained for the area of installation by the
use of correct arrangement of cable & gland & sealing and in

Where other certified components are part of the assembly, the user
must take account of any limitation listed on relevant certificates.
These instructions assume that the required cable entries have been
pre-drilled (and may be threaded) on the terminal box. The cable
glands are usually fitted during installation.
The terminal box must be installed in absence of damage and free
of defects.
